ABSTRACT:
An optic disk drive includes an outer casing inside of which an inner casing is received to define two side channels between side walls of the outer casing and opposite sides of the inner casing. A disk holding arm is pivoted to and extends above the inner casing to define a spacing therebetween for receiving therein a disk tray which supports an optic disk thereon. The disk tray has two side flanges, each having a step-like configuration, slidably receivable within the side channels between a retracted position and an ejected position. The vibration absorbing device includes a C-shaped resilient member fixed to each of the side walls of the outer casing and having a contact segment extending into the side channel to contact and form a resilient engagement with the step of the disk tray when the disk tray is at the retracted position. The vibration absorbing device also includes an anchoring member provided on a rear side of the disk holding arm to contact and thus engage the disk tray when the disk tray is at the retracted position so that when the disk tray is at the first position, the vibration absorbing device provides a three point contact engagement with the disk tray to tightly hold the disk tray against vibration.
